The Difference Between Dysport And Botox

difference between dysport and botox, anti-aging, fillers, dermatologist

Dysport and Botox are both neuromodulators, derived from neurotoxins (forms of botulinum toxin type A) that have been approved by the FDA to minimize fine lines and wrinkles. They are both minimally invasive injectables that are equally safe, and they both work via the same mechanism. They temporarily paralyze the muscles of the face, which reduces wrinkles and smooths skin. While both products are used for the same purpose and are chemically similar, there are a few key differences between the two. It is important for patients to understand the differences so that you and your physician can choose which one is right for you.

Dysport injections, Botox injections, reduce wrinkles


Dysport is a neuromodulator derived from botulinum toxin. It temporarily paralyzes the muscles in the face that cause repeated muscular contractions that then lead to wrinkles. Dysport is injected under the skin to treat moderate to severe wrinkles caused by motion. The 11 lines between the two eyebrows are where the deepest wrinkles are located, and Dysport is frequently used to treat this area. Dysport is also used to treat the forehead, crow’s feet, bunny lines, and can be used around the mouth to create a “lip flip.” Dysport is a temporary solution for wrinkles and the results last from 3-4 months. After 3-4 months, a follow-up injection is necessary to maintain the smooth look.

Botox works the same way as Dysport, as it is also a neuromodulator derived from botulinum toxin. It blocks the nerve signals to your muscles, which results in a more relaxed and softer look on the face. Dysport was used in Europe before receiving FDA approval, however, Botox is exclusively used in the US. Botox is injected by a physician or dermatologist and requires little to no downtime. Botox is used to treat the same areas as Dysport. The exact number of units needed will depend on each individual and the severity of the wrinkles. The results of Botox may take longer to appear than Dysport, but both products last the same length of time; around 3-4 months. Repeated Botox injections are also required to maintain results.

Dysport vs. Botox: What are the Key Differences?

  • Dosage: The most important difference between Dysport and Botox is the fact that they are dosed differently. Fifty units of Dysport does not equal fifty units of Botox. An experienced physician will inform you of the right dosage for you.
  • Molecule Size: Dysport’s formula contains smaller molecules compared to Botox, which allows the smaller molecules to work faster than the larger ones found in Botox, and it covers a larger area. It is crucial to use an experienced physician who is an expert in proper dosing and placement of whichever neurotoxin you choose.
  • Diffusion: Dysport tends to diffuse more than Botox, which causes it to spread to a broader area after it is injected. This means a larger area can be addressed in fewer injections.
  • Onset: Dysport has a quicker “onset” of action compared to Botox, as Dysport results are typically fully realized in about 24 hours. Botox results can take up to 72 hours to fully appear. Dermatologists advise their patients to give both products a full week to see maximum results, as every person may vary in response time.

Is Botox Better Than Dysport?

When Botox is injected, it stays in place in the injection area. Because of this, Botox is a good option for treating smaller, more targeted areas. Dysport is diffused into larger areas after injection, which means that it spreads out from the injection site. Dysport is ideal for treating larger areas, such as the forehead, because fewer injections are needed to address a larger treatment area.

Dysport vs. Botox: What are the Similarities?

Over time, fine lines and wrinkles will naturally develop in areas of the face because of repetitive muscle contractions from normal everyday facial movements or expressions. One example of this is smiling and squinting which creates “crow’s feet” around the eyes.

Both Dysport and Botox treat fine lines and wrinkles by relaxing muscle tissue to the point where they prevent the muscle from contracting. Either product is injected into a targeted muscle area, causing the nerve impulses that control muscle contraction to be temporarily blocked. The resulting decrease in movement and relaxation of muscles reduces the appearance of wrinkles in the area.

The results of both neurotoxins are temporary. After a period of time, the nerve impulses begin to reach the targeted muscle area again, which results in both muscle contractions and wrinkles and fine lines reappearing. An experienced physician can maintain the positive results of neurotoxins with regular sessions approximately every 3-6 months.

Is There A Difference in Results? 

Both Dysport and Botox work in a similar way and provide similar results. However, the major difference between the two is when the results are visible. When receiving Dysport injections, patients may begin to notice results in as little as 24 hours after treatment. When receiving Botox injections, final results might not be noticeable until 72 hours or more after the injections.

Dysport comes in smaller units, as one unit of Botox is equal to 2 units of Dysport. However, this does not mean you will pay double for Botox. Both are similarly priced, as one unit of Dysport costs about the same as half of a unit of Botox. The exact amount needed will depend on each individual and what the specific cosmetic concern is.

Which One Lasts Longer?

The results of Dysport typically last about 4 months, while the results of Botox typically last between 3-6 months from the initial injection. The exact result duration can vary from patient to patient as there are many variables, such as treatment location, muscle size, metabolism, and skill of your injector.

It is important to know that the results of either Dysport or Botox can be extended by receiving periodic maintenance injections. After about a year of receiving Dysport or Botox treatments, many patients can go longer between sessions, and a smaller dosage may be required in order to see results.

Which One is Safer?

Both Dysport and Botox are safe when used as directed. The most common side effects are redness, minor swelling, or itching at the injection site. Rare side effects include droopy eyelids or muscle spasms. Botulinum toxin poisoning is another rare occurrence, which can occur in those who have an allergic reaction to the drug, or in those who receive too many injections in a short period of time. These reactions have only been reported in patients receiving botox at high doses for non-cosmetic reasons, such as muscle spasms. An experienced physician will ensure that you are not experiencing any serious side effects. It is important to use an expert physician, preferably a board-certified dermatologist to minimize these effects.

Which One is Cheaper?

While Dysport and Botox may have different pricing per unit, both will end up costing around the same to receive similar results. Prices will also vary from injector to injector, which may be an indicator of training and experience. When it comes to your face and cosmetic treatments, we recommend choosing an experienced dermatologist over a bargain to ensure the highest-quality and most natural outcome. (You can reword this to sound better). Call your local dermatologist for a consult in order to find out the exact cost to you.

The choice between Dysport or Botox may be a simple preference by both the physician and the patient. Both products are safe, however, outcomes depend on many factors. Both products last anywhere from 3-6 months, however, the exact time varies from patient to patient. Both offer similar results, and the choice is up to you and your dermatologist.
